Ehhh no they never said any of that. They had nothing against cities and organizations. They just helped restore them to balance when things got out of control. They said they were a check against human corruption for thousands of years.

It helps that Nolan expositions the hell out of his villains motives. It makes it easier to show how TDKR's LOS was wrong.

Honestly, the LOS' motives in BB was utter ********. It made absolutely no rational sense. There is no such thing as a "moderate" terrorist organization. They're called extremists for a reason.

I always just figured Ra's was ********ting Bruce to convince him to go along with the LOS' plans. Which is something he did like constantly in the entire movie.
